IMPItovnI/IENT III TIRE-SHRINKING IIIID- PUNcHINe MACHINE.

TO ALL WHOM IT MY'CONCERN:

Be it known that I, WALTER BRITTON, of Abingdon, in the county ofKnoX,and. State of Illinois, have invented a new and useful-Improvement iriTire-Shrinking and :PunchingMachine;` vand I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skiled in the art tol make and use the same, referencebeinghad to the' accompanying drawings, forming Pli 0f thisSpecification, in whichi i i Figure 1 is a side view offmyimproved'machine', having a part thereof shown in sectinm Figure 2 is aplan 'View of the same.

Figure 3 is a detail section ofthe same.

Figure 4.2 is a detail cross-section through the line 'rv 11;, fig. 3.

Similar letters of reference indicate-like parts', I

The obj-ect of this invention is to accomplish the shrinking ofwheel-tire-i'nan improvedmanner. It eo'nsists of the parts set forth inthe following: i i i AThe general frame ofthe machine is shown a't-A,having legs, B, and a. rod, C, for holding themaehine to the Hoor.` Theplate D is provided with slotted lugs a a, bolted or otherwise affixedtoit, as shown, and' this plate is actuated forward by the cam-levers E,and returned by the spring bi The lugs e e are boltedv to vthe plate Grby the bolt c, which passes through the frame-plate G, as shown.

The top vplate H, which covers `the lplate D in part, is connected withthe frame-plate G by means of boltsor rivets d d d, which also serve asguides tothe plate D in its to-andfro movement. The spring b is aiixe'dto bolt d', and its reduced end rests in a hole in theplate D, as shown.

The bolt in plate g serves to clamp the angular' guide-plates'hto thefra-me A, and 'also assists to hold the lug-plate e moreiirmly. It alsovserves to'providc a restfor the tire I, (when the same is being shrunk,)and to' hold the same level with the bottom of thelugs a a, as shown. I

The tire is heldrmly to the plate D. by a key,`Jf, which is slightlytapered, and is driven through the slotted lugs a a, as shown.

l A similar key, K, holds the tire fast to the plate g. When thecam-levers are in the position shown, the plate D is at its Aremotestposition from thelugs e e.

'The heated tire is -placed in the lugs and keyed fast, and thecam-levers being actuated-b`ackward, the tire is compressed or shrunk,as will be obvious. Y

The angular plate z' serves asa guide for the front end ofv the plate D,as shown. A When themachine is to be used for punching holes, arest-plate, L, havingelamp-.edges,'l, is set on'the frame, in theposition shown, the said clamp-edges bearing against the lugs e therebysustaining the thrust strain'upon that point, tllepunchings passingthrough the hole m in the ordinary manner.

Theipunching-.plate M is provided with a corresponding punching-point,at. This plateris held by a. tapered key, N, as shown atg. 4. 4 i n vThe punching-plate being thus keyed to the plate D, is actuated by the'cam-levers in the obvious manner. The bolt o, upon which the cam-leversvibrate, passes through the top plate H and the frame-plate G, as shown.

This machine is simple, of small cost, and easily operated, and suppliesa want long felt'in small smitheries. A smallerliey, g, holds the plateL ruly in place.

VHaving vthus described my'invention, I claim as new, and desiretosecure by Letters'Patent- 1. The plate D, bearing slotted lugs a a,the cam-levers E E,spring b, in combination with the frame-plate Gr,slotteddugs e e all constructed, arranged, and operating substantiallyas shown and described, a.nd for the purpose' set forth.

2. The plate and punch M and n, and stirrup L, for joint use with thesubject-metterci' the'preced'ing claim, inthe manner and for the purposedescribed.

WALTER BRITTO'N.
